Top to bottom US-made

Outsourcing is not a minus on its own but, based on what we’ve seen when it comes to memory foam, there is a pattern. The quality ratings of the foam with the same density and firmness start to vary with prolonged use.

We revisit and update the quality ratings at 1, 2 and 5-year marks. Based on what we’ve seen, the gap in ratings (shape retention and structural integrity) appears at these time milestones.

A big plus

Statistically speaking, those ratings speak in favor of US-made foam. To be clear, we don’t want to make a blanket statements, and there are companies out there that import foam that stands its ground when compared to a US-made product.

To simplify – all we want to say here is that an average buyer can be more comfortable with spending money on US-made foam that passed all the rigorous testing and obtained the staple quality certificates.

That’s what the Shiloh is made of and, if you ask us, it’s a big plus.

Foam quality95%

What we expected to see

Having in mind that Sleep Innovations are making an effort in their advertising to stand out from the crowd by stressing that there is no one-size-fits-all mattress, we expected the Shiloh to be top-tier.

Why?

Because a company like this wouldn’t risk their reputation by putting a product on the market that’s sub-par compared to the manufacturers they’re trying to distinguish themselves from.

What do we mean by that?

The Shiloh is designed to be a good fit for most people. In a market where many companies simply make one mattress and advertise it as one-size-fits-all, Sleep Innovations is an exception.

They make a range of mattresses for different body frames. The Shiloh is their flagship product with the widest appeal – average to large person.

In other words – it’s designed to find the sweet spot between comfort and support.

Airflow and heat dissipation of the Sleep Innovations Shiloh 12-inch

The foam used to make the Shiloh is patented, with cell structure designed to improve airflow and heat dissipation.

We wouldn’t go as far as describing it as “cooling”, but the heat dissipation numbers we’ve seen do justify the claims the company makes.

In that quality aspect, it belongs to the top 5% of mattresses we ever analyzed.

Firmness vs. support90%

It might not be right for you if…

If you prefer an extra soft feel, this mattress might not be right for you. In terms of firmness, we would describe it as medium.

That doesn’t mean much on its own

When you’re looking to buy a mattress, the proper analysis should include “firmness versus support” rather than each of these separately.

Based on the pool of numbers we have, we’d say that 8 out of 10 people will find this mattress to be “just right.”

Here’s why

Shiloh is not just a lump of foam. The layers work together to balance between firmness and support.

This means that the top layer (2.5 inches thick SureTemp foam) is there to allow your shoulders and hips to sink just enough for proper spinal alignment. The SureTemp foam is trademarked by Sleep Innovations and 3rd-party tested to do what the company claims in the advertising.

The base layer is denser and thicker (9.5 inches). It’s the base that’s “responsible” for the structural integrity, shape retention and support.

To be more precise

Putting it simply – for body frames ranging from medium to large, the Shiloh is at the sweet spot. The base is just firm enough so that your spine doesn’t arch downwards, while the top has enough “give” to prevent the spine arching upwards.

That especially goes for side and back sleepers.

Hot versus cold sleepers

In terms of heat dissipation, the only scenario where Shiloh might not feel right is if you’re an especially cold sleeper and the temperature of your bedroom is also low.

In all other scenarios, the mattress does a solid job of both dissipating heat and not trapping the cold. The user satisfaction numbers we’ve seen were slightly higher with people more concerned about heat retention.

Airflow and heat dissipation of the Sleep Innovations Shiloh 12-inch

Before we get into this, let us just mention that we have separate statistical model when we rate all-foam products (different formulas from those we use for innerspring and hybrids).

Why?

It’s because you can’t reasonably expect the same level of edge support from foam and mattresses that have a thick wire encircling the edges.

To put it simply – it only makes sense to compare apples to apples.

With that said, this mattress belongs in the top 10% in its category.

What this means for you

It means that the edge support is nothing to write home about, but we also don’t see it as a red flag.

It’s solid enough to sit on the edges as you preparing for sleep, but you might find it too soft to read a book or watch TV show while seated on the very edge.

Motion Isolation

This is where Shiloh truly shines. With the layered structure in mind, this doesn’t come as a surprise.

To be honest, the motion isolation properties contribute less towards our final ratings than other quality factors.

Why this rating doesn’t carry as much “weight”

We all remember those commercials with a bowling ball dropping on a mattress without spilling a glass of wine.

It is impressive when you see it, but how many times did you actually wake up because your sleep partner was moving too much?

Our guess is – not many.

The bottom line here is that Shiloh has excellent motion isolation properties, but we wanted to be clear that we find other quality aspects more important.

Durability & longevity

There’s confusion with the terminology here and we want to address that first.

Maintenance

Since the structure is not symmetrical, the mattress should not be flipped.

Many of us are still trapped in the perception that flipping a mattress will prolong the lifespan.

With modern mattress technologies and materials, it’s not so simple.

Here’s why

With mattresses that shouldn’t be flipped, the manufacturer has to be extra careful, especially when they offer a 20-year warranty.

This means that they have to make sure that the structure can take the prolonged use and maintain shape.

Otherwise, they would be faced with people claiming their warranties too often, which would affect their bottom line.

The important part here is that the numbers we’ve seen when it comes to foam breaking or indentetion development with prolonged every-night use are low.

Rotation

The mattress is symmetrical (side to side) which means that you can rotate it but, based on what we’ve seen, the number of people who feel the need to do it is very low with the Shiloh.

This ties into the analysis above and means that the number of people who saw structural issues is also low.

To put it simply – there are no indentations or uneven surfaces forming over time that would call for the mattress to be rotated.

What does the 20-year warranty cover?

When you see a long warranty like this, you should be careful and make sure that you read the fine print. In some cases, a company can “dilute” the warranty terms and you might end up with additional cost when making the claim.

We looked closely and saw no red lights here, the company does what it promises – covering the full cost related to any warranty claim (replacing or repairing the bed).

These terms cover any issues with the fabric, stitching and, most importantly, potential structural defects.

Bounce-back – secondary

What we mean by “bounce-back” is the time it takes for the surface to get back to its original shape when you get up.

There are two ways to look at this.

Apples to apples…

The first way is absolute (comparing it to every mattress out there) and the second one is comparing it to mattresses in its price range.

If you do the former, it’s fair to say that there are products out there with higher bounce-back ratings. They do, however, cost much more.

If you do the latter, this puts the Shiloh in the top five products in its price range.

Why it’s a secondary factor?

Similar to the motion isolation, we don’t see the bounce-back as a crucial factor simply because nobody ever said, “I got up to go to the bathroom and when I got back my mattress wasn’t completely flat.”

That’s why our statistical model includes the bounce-back only as a secondary factor.

The history – SureTemp & Shiloh

The mattress hit the market back in 2010 (May 15, to be more precise) and was initially known as the Sleep Innovations SureTemp. So if you see it under that name, don’t get confused, it’s the same mattress.

The name SureTemp was a way for Sleep Innovations to stress the trademarked foam used for the top layer.

Cover quality

The number of garment issues (stitching tears) reported by the owners we talked to was lower than those we’ve seen in 93% of other mattresses.

Quilted vs. smooth cover

To be subjective for a moment, we prefer the quilted cover over the smooth one. It feels more rugged and durable and looks more luxurious.

But when it comes to the numbers, we’ve seen no substantial difference in abrasion percentagess or stitching.

We rate the quilted cover at 92/100 and the smooth one at 90/100.

These numbers are based more on our experience than the actual testing (the data pool we had here wasn’t big enough to do that).

Apart from the aesthetic appeal, we find that the rugged covers are typically superior in terms of stain release.

Value for money

When all said and done, this is the category that probably does the best job of reflecting overall quality.

If you didn’t take the time to read the full analysis, let’s go over the basic takeaways.

Top 6 %

In most quality aspects, the Shiloh 12-inch performed superiorly compared to mattresses in its price range.

Most of the time, it tested just as well as mattresses that cost anywhere from the 200 to 400% more.

Our rating of “value for money” is 95/100, which puts it in the top 6%.

We have five descriptive categories that we use to rank mattresses in terms of value and the Shiloh belongs to the top one “Worth every penny and then some.”
